I retired in 2006 and bought Mathematica and a stack of math books with the goal to teach myself to become a world-class mathematician. I am on pace to achieve that goal sometime shortly after the next Ice Age.

I consider myself a Mathematical Mutt (no papers) who occasionally ventures off the back porch to play in the yard with the big dogs.

I donate regularly to the The OEIS Foundation.

When I look at the patterns, I can hear the wheels turning. When I look at the math, I find out the hamsters have died.

The observation about the discontinuities is the answer.

+1 for the great analysis. I'm reviving hamsters as I write this. The link to Pippenger in the OP has something similar for the $n$th steps.

@CoreyKelly, I put the results into the OP, so it is more easily read.

@CoreyKelly, I don't. The results before the LH power of two is applied: $\frac{\pi e}{8 \sqrt{2}}, \frac{\pi}{4},$ and $\frac{e}{2 \sqrt{2}}$. I'd hoped that this pattern could be exploited.

@0x4A4D, I want $\frac{\pi}{2}$ and $\frac{e}{2}$ for the results of the first two calculations.
